Here's RestoRick's Web Site, but it doesn't have much info on the project. Have there been any updates? I think this would be agreat little engine, too, and I'm keeping my eyes out for a good opportunity on a late-model one. The 2008 models got a pretty significant upgrade, and make 303hp @ 5650rpm and 330lbft @ 3950rpm. Those are almost the exact same numbers that my warm 340 make right now, and I'm sure thre would be a significant mileage increase due to smaller size and roller everything. The 4.7 will bolt up to any LA bolt pattern trans, but it's got (IIRC) an 8-bolt crank flange that is NOT the same as the old Hemi 8-bolt flange, so manual trans applications will require a custom flywheel. Keep us posted! Clair

I spoke with a Chrysler tech who said he'd done a couple with using the factory harness and weeding out the emissions related plugs. I can't remember what he said about trouble codes this would generate... I'm guessing it'd run in a limp mode?
I did this when converting an 80's carb 2.2 to EFI. It worked and did not run in limp mode, but the 80's emissions equipment was crude in comparasin to what we have today. It was a ton of work to sort through everything and wire it all up. Then when all is said and done, you're still hammered by the lack of tunability. IMO an aftermarket EFI controller would be worth the cost.

If you're going to run an essentially stock system anyway, why not run the stock ECM/PCM if you can? No tuning needed on a stone-stock engine/trans, you just need to convince them that they're in Durango/Dakota/Ram/Whatever they came in originally. No reason you couldn't install the emissions items necessary to keep the ECM/PCM happy. There's not much to be gained by ditching the converters, especially if you go with a couple decent high-flow units. For that matter, you could go with just one in a single 3" pipe and either split to duals after the axle, or heck, right after the cat. A buddy of mine just did a similar swap with a new Hemi in to his 93 Ramcharger, and it turned out to be a great package. The only thing that doesn't work that used to is the cruise control. He thought he could learn to live without that...

Hi Clair, Mine is from a 2002. I checked out schematics in the factory manual (CD) and it seemed to be tied in with gauges too... other things I can't recall as well. (it's been awhile ) To get all the emissions pieces might be a nightmare too. I've considered picking up a parts truck to rob parts from too, but it seems I'd have some pretty serious $$ tied up in that route. I suppose a late model boneyard is an option too. I'm all ears for any suggestions... cool on your buddy's Hemi into the '93 Ramcharger !

Yeah, the OP is probably going to need to go aftermarket if boost is in the plan. Duner managed to boost the snot out of the 4.7L in his Dak, but I forget how he managed the extra fuel. I think I remember that it was some sort of external FMU, but I've slept too many times since I discussed it with him. Sounds like RestoRick may be keeping it stock for a cruiser, so maybe the OEM stuff would suit his needs. Although I'd love to have a stock 303HP 4.7L under my hood, I don't know if I could keep my hands off it, either... At least I wouldn't have to worry about running the auto trans, too.

Well... While a basic cruiser is the plan, I could very well play with it more down the road. What are some EFI controllers worth looking at? I've googled and come with a bunch for motorcycle applications... also the multisquirt. Clair, "LS engine controller"... what is that? Rick

You would think that F.A.S.T. would have something. How about ACCEL? I'm really interested in this little project, I always thought the 4.7 was a torquey engine in the Dakota. With a little tuning, should run 350 hp easy, I would think.

Rick, The "LS" engine controller is one of many/any that are capable of running one of GM's LS-series engines. These generally have sequential injection, distributorless ignition, coil-on-plug ignition, etc. As with many GM control systems, even the OEM parts have a bunch of aftermarket support and some tuning capability. I think an LS-1 system was used early on as a stand-alone system to run the new Hemi, so the 4.7L shouldn't be too hard to adapt, either.
